Adorable Zoo Babies: Newborn Jaguar

The most recent gator is a little less shy, coming into view of neighbors and wildlife experts while taking a lazy swim down the river early in the day. It was intially spotted Sunday.

The gator is between three to five feet in length with a yellow and black striped tail and a green body.

"He was kind of hiding under a rock and it looked like he was eating something under water," said 8-year-old Kaleb Berry.

"It looks like a baby aligator that's maybe spent a few weeks out there. It doesn't look like something someone kept recently in a cage. It looks too big for that, but it looks pretty happy, just hanging out in the sunlight," said Kamran Sadr, who snapped photos of the reptilian visitor.

It’s unclear where the spate of gators originates, but experts suspect they are discarded pets.

"This is an alien species. This is a dangerous animal," said Bob, a volunteer for the Chicago Herpetological Society who declined to give his last name. "It's an endangered species. It doesn't belong here where kids can play around. I mean, there are little kids here. If they go down there catching frogs or try to fish, and suddenly they reach down to grab a frog, and that frog turns out to be a pair of bulging eyes of an alligator."

Traps baited with chicken drumsticks and rats have been put out in hopes of catching the gator.
